halt on one side and the second hall on the other side. the mechanism ofthe present invention, am able to absolutely dispense with the use ofguiding, margins and thus eliminate the elements of error aboveret'erred to. it, is to he understood that the error caused by thedeflection of the wire above reterred to. resulted in irri-yqularcutting; of the blocks. that is to say, the bricks To all whom it mayconcern:

Be it known that liowinn K. Kine. a citizen of the l uited States,residing atv Philadelphia in the county or Philadelphia and State ofPennsylvania, have invented a new and useful Brick-Machine, of which thefollowing is a specification.

lily invention relates to wire cut-oil mechanism t'or brick machines.

The object. of my invention is to provide improved means for supportingand moving the cut-off wires in planes at the required angle through thebar during; the travel of the bar.

The invention comprises improved means for the independent adjustment ofthe sup porting mechanism for each end of the wire and improved meansfor providing a positivc drive to each of said inde 'iemlentlyadjustable supporting means.

My invention also comprise, automatic means controlled by the travel (itthe bar for aliectingr or -:)ntrolling the positive drive of their otherextensions, but were slightly inclined or wha '1 are known as skewed. Another feature of the structure described in said patent was that thecut-oil mechanism was positivel driven through the measuring! pulley.supplemented by a helping; belt driven from the main source of power.The tension of this helping belt was adjusted by a screw hand wheelacting on a spring; lever,

conununicated through the hel 'iing belt to the normal requirements ofthe traveling bar, but it is to he noted that this adjust travel ofthere was no automatic change in the adjustment: to correspmnl and thusundesirable results were likely to occur.

My present invention comprises means for overcoming this objection.

Iii) invention also comprises details in coir struction mainly devisedto accomplish the results above reierrcd to.

C ne oi the impo nt features of the pres ent invention con. in the itthat the inner ring and oauer ring are each independently supported andadjustable, and each positively (.lriven, so that the wire is carriedthrough the clay bar in a plane accurately cut at right angles with itslongitudinal extension.

'iwo important features oi the present mechanism are the positive hiveof both rings. and the independent adjustment of the plane of niorenientoi? each ring, so that there is a positive support tor each end of saidwire actuating means. ment was not a variable or automatic ad- Thisinvention coinnrises improvements on .l e and when the Speed of the claybar suddenly changed,

the mechanism described in patent to King and Chambers l lo. (37825.);July 9, 1901.. liet'errinn' to the machine described in said Pat ent678.259. it is to be noted that the outer ring, which supports one endot' each wire, is actuated solely by the inner ring 16 through. thewires connecting said two rings. As has been explained in thespecification of the patent it was impossible to an absolutely straightor right-angular cut of the bar by this mechanism without the use of a,guide slit, t rat is without utilizing the margins of the slit fordeflecting the wire from the position it would otherwise assume, andnotwithstanding this it was a fact that when the wire was passingthrough the clay bar the resistance caused therel'iy resulted in the ordeflecting of the wire. the tendency being to deflect it at rightanglesto the travel of the bar, and this was due both to the yielding; of theouter support of the wire and to the lag caused on the supporting ring 15 A f fl (ja gg f 1g th i ldthe wire. which makes it possible to secure12 r bgyi jng: of the Vi -e E ge 3113 if the required lllUl'ellltllt(ll? lllQ \Vil't l lll'Ollgll gliis g epancy was i nposgible to get, anat the bill Of clay, l' Oi-e lji'iOliS 0i? di'ii'erent sizes, solutelyaccurate out even by the us f th to secure the cut in a plane ut rightangles with the bar's exrrension.

Adjustable wire supporting me(ms.Referring to the wire supporting andmoving mechanism as best shown in Figs. 2 and 3, the inner wheel or wirering 40 is supported on the shaft 41 in journal box 42 adjustablymounted on the portion 43 of the stationary framework of the machine.This wheel or wire ring 40 is provided with gear teeth for cooperationwith the driving pinion 44. Said journal box 42 has a pivotal connectionat 45 with the stationary frame 43, and is adjustable about said pivotwithin the range of movement permitted by the slots 46 through whichproject the fastening bolts 47. The outer ring or wheel 48 see Figs. 2and 3, is mounted on the rollers 49 and is guided at the top between tworollers 50 and 51 as best shown in Fig. 25. These wheels 50 and 51 andalso the rollers 49 are supported on a stationary ring which isadjustably secured to the stationary framework. The adjustable method ofconnecting the ring member 52 with the stationary framework is clearlyshown in Figs. 19 to 21 inclusive. Said ring 52 having a pivotalmovement about pivot 53 and within the range of movement between bolt 54and slot 55 shown in Fig. 21. A further adjustable fastening meansconsists in bolts 56 in slots 57. The wire ring 48 is also provided withserrations or gear teeth on its side for cooperation with the pinion 58.It will thus be seen that the supporting structure for the inner ring 40has an adjustment about the pivot 45, while the outer ring 48 has anindependent adjustment about the pivot 53. The centers of said pivots orthe axes of movement of said ring supporting means, are approximatelycoincident or lie approximately on the same line, when projectedtherethrough as indicated in Fig. 3. The adjustment of inner ring 40 isindicated on the scale 171, Figs. 3 and 17, while that of the outer ring48 on the scale 172 Figs. 8 and 21.

Actuation 0; wire rings.1t will also be seen that each wheel has apositive drive from its respective pinion both mounted on the same shaft59. By this means each end of each wire will be carried uniformly andpositively so that no distortion or error can be caused by the res'tance to its movement as it passes through the clay, and that since bothrings are capable of independent adjustment it is obvious that suchadjustment may be made as will insure an accurately rectangular cut ofthe bar without resorting to any guiding efiect of the slit plates, andthus the element of error inci- C ent thereto as above described iseliminated.

The pinions 44 and 58 are mounted on shaft 59, carrying pulley 60 whichis driven tln'ongh belt (51 by pulley 02. on. shaft 03, which is gearedthrough pinion 0-1: with the en wheel on shaft 0? of the le 1 pulley 07.The movement of regulating pulley 07 is normally controlled by themovement of e clay bar. The hel ing power for cooperating with theregulating pulley be described iollows: Elie re tulating f 'amc 71 iscarried by the r' llers T2 at one end, see llig. 0, and at the other endis pivotally mounted on the frame '73, see

Figs. 0 and 10. Extending froin the end of the regulating frame is thebracket 7%. see 5 and which supports the thrust box '75 secured on theend of shaft 03, see also Fig. 11; it being understood that this bracketis integra with the journa b' x of shaft 00. The sha has loi'igitiuliualmovement through journal boxes so that it will be evident that anymovement forward or rack of the regul; ing frame will effect. theehniency of engagement between the friction elcncnts 0 and 70. Se airedto the stationary framei'orl-z of the device the spring '70 regulated bythe tension whe l 77. This tension spring has an opera tive connectionwith the regulating frame through the rod i8, which is pivoted, to theframe at 79 and has an engagement with he spring at 80. The action ofthis spring '70 to press the frame 71 in the direction of the arrow, see5, which through the thrust lQOX 7'? ca ried on bracket tends to pullthe shaft (13 in the direction of the arrow, see Fig. 11, and therebymaii'itain an etlicicnt eng ement between friction elcnients 0.0 and T0.it will thus be seen that by a nice adjustment of spring 70 the amountof help normally desired from the shaft 08 to the shaft 3 will besecured for the actuation of the wire rings 4-1 and 48. ll is also to benoted that snaft 03 is geared through pinion. 04c and gear 05. with 1ft00 of the measuring pulley 07. iVhen the move nent of the clay barcarried by the measuring belt 81 is accelerated, it tents to push theframe 71 forward and adds to the pressure exerted through sorino; to '4)increase the efficiency of engagement between the, friction .Vhile onthe other clay bar is retarded in its slat-ing frame 71 will be elcmcn's0 and 70. hand, when the travel. the req pulled backwar 11 opposition tospring which, tln'ough the connecting mechanisms above described, will.tend to separate and thereby diminish the eiiciency of engagementbetween toe friction elenusnts 09 and T0. in this way is secured ahighly responsive automatic adjustment, controlled by the travel of theclay bar, for regulating the n'iovemcntof the cutting elements to correspono with the movement of the sa d clay bar. Any iation tending toexist between the speed of vol. of the bar of clay and of the regulatingbelt is immediately transmitted through the regulatiig table to thefriction device. whereby said variation neutralized and the re i-latingbelt: and the cutting ineehanisn'i are 'i all times positively driven atthe same speed with that. of the bar of clay.

it is to be understood that shaft 68 is always driven at a. speedgreater than that of shaft 63, that is at speed greater than shaft (333will ever be required to attain. It thus follows that the engagementbetween the elements 69 and '70 is always a arving slipping engagementand by the automatic adji'istmcnt between said elements (it) and '70 asabove described, the movementof the cut-off mechanism and the mow-uncutof the. regulating belt ar always maintained relative to the varyingspeed of travel of the bar, notwithstanding the fact that the speed ofmovement of the main driving shaft 01 is constant.

Tlzroeaaouafi and brake for cut-077 77Z(?C']I(7?- 'Zsm.ln order tointerrupt the operation of the cut-off mechanism. without stopping themovement of the clay bar, since it is sometimes necessary to replace avbroken wire on the cut-off rings, and it is undesirz ble to interruptthe movement of the clay through the machine for reasons well known inthe art, I provide the following mechanism: as already pointed out,power is communicated fron'i pulley 62 to shat 59 through belt 01running over a pair of idler pulleys 1.00 and 107, see Fig. 1. Pulley106 is mounted on a bracket 108 carried by the saaft which is slidablymounted on the bracket 109 which is adjustably connected with thestationary framework of the n achine, Figs. 23 and 24. On one end ofshaft 105 is secured the member 10a having one end 110 projecting intoand adapted to move in the channel 111. This is to prevent the turningof the shaft while permitting its longitudinal movement. At the lowerside of member 104; is pivoted at 112 the connecting rod 103, which issecured a t its other end to the crank 102 on shaft 101. To the otherend of sl aft 105 is secured the brake shoe 11% which adapted tocooperate with pulley (E0. Shaft 101 is connected by the universal joint100 with the shaft 99 which extends across the machine and is providedother end with the hand lever 08, see Fig. 1. By shifting lever 08 inone direction the pulley 106 is moved toward pulley 60, thus slackingthe belt thereon and at the same time brake 114 cooperates with the saidpulley 60 to stop its rotation. By moving the lever in the otherdirection the pulley is returned to the normal position and the brake ismoved away from contact with pulley 60.

Adjustment of pinions.-As already stated the wire rings 40 and 48 areindependently adjustable, the one about center 45, the other about thecenter 53; the said centers being on a line extending through the saidaxes. The gear wheels 44 and 58 are ournaled in the framework or bracket109 which is se cured on the stationary framework by the fastening bolts115 projecting through slots 116. The movement of this bracket 109 tobring the gears or pinions 44 and 58 into proper relations with the gearteeth on the wire rings 40 and 48, after the same have been properlyadjusted, accomplished by the adjusting screw 117, see Fig. 24, threadedinto the stationary framework and engaging with the lug 118 of guidetongue 119. which is secured to the underside of bracket 109.

Tension control of regulating belt.The means for securing the necessarytightening or tension of the regulating belt may be described asfollows: The frame 120 is slidably mounted on the regulating frame 71 asshown in Fig. 6. On the die end of this sliding frame 120 is journaledpulley 121 around which passes the regulating belt 81. This frame 120 isengaged with the screw 122 threaded into the member 123 which is securedto the regulating frame 71 so that the distance between pulley 121 andthe regulating pulley 67, may be increased or diminished by turning thescrew wheel 124 in one direction or the other. The intermediate portionof the regulating belt is supported as usual upon the series ofsupporting rollers 125.

Construction of roller journals-The roll ers 125 for supporting theextension of the regulating belt 81 between pulley 121 and theregulating pulley 67 are journaled in the journal boxes 126 which areloosely seated in the T-irons 127 which are connected with the sides ofthe regulating frame 71. These journal boxes 126 are adapted to alinethemselves with the journals 130 of said rollers 125 and are thenloosely secured in place by the bars 131. By this simple construction issecured the automatic alinement of the journal boxes with the journals.

Vertical adjustment of regulating frame.- The vertical adjustment of thedie end of the regulating frame is secured as follows: The rollers 72upon which this end of frame 71 rests, are journaled on uprights fromframe 132. This frame 132 has av tongue adapted to project into avertical channel or groove in the stationary member 133. A screw 134projecting upwardly through the base of the machine is adapted to engagethe underside of member 132, to secure any desired vertical adjustmentthereof, while the bolt 135 is adapted to lock the members 132 and 133together when such adjustment is secured.

Adjustable means for maintaining the proper relation between gears 6,4and 65. Referring to Figs. 11 and 35, it is to be noted that shaft 63 isadapted to have a longitudinal movement in its journal boxes, and thatit is normally maintained by the action of the spring 7 6 through theregulating frame 71 and thrust box 7 5 in position to maintainengagement between friction elements 69 and 70. It is also to be notedthat the shaft 63 is to be maintained in such position as to preservethe proper relation between gears 64 and 65. It will be obvious, from aninspection of Fig. 35, that the element 136 at the end of shaft 63 has abearing against the plate 137 of the thrust box 7 5, and that as thefriction surfaces of these two members wear, it is necessary to take upsuch wear to maintain the gears 64 and 65 in the desired relativeposition. F or this purpose I secure the thrust box 7 5 to the bracketmember 74 by the screw 138 provided with a spherical head 139. Byturning this screw in one direction or the other the required adjustmentbetween thrust box 7 5 and bracket 74 is secured, and consequently thedesired relative positions of gears 64 and 65 are secured. The pin 140is adapted to project through apertures 141 in said head, there beingtwo transverse apertures, and said pin is adapted to cooperate with theaperture 142 in bracket member 74 normally to maintain said screw 138 inany desired position of adjustment.

Adjustment of journal bearing for shaft 68.The proper adjustment of thejournal bearing member carrying the shaft 68 of the thrust collar 144,with respect to the other operative parts of the machine is secured byproviding the slots 145 in the base 146 of the journal box member 143,so that a certain amount of play is permitted therein, in adjusting saidmember 143 to the base 147 of the machine by the fastening bolts 148. Bythis means wear between elements 69 and may be taken up and the elements69 and 70 may assume the proper normal relative position, with thepivoted frame 73, supporting the front end of the regulating frame 71,in the strictly upright position.

Construction of rolls l9.B-olls 49 cooperate with rolls 50 and 51 insupporting the wire ring 48. Each roll 49 is provided with a rim havinga removable portion 149, which is adapted to be threaded onto the
